Summary:

Researchers developed and tested a prototype Intelligent Drum Line system that can detect speeding drivers as they approach a work zone and deliver visual and audible warnings to attract their attention before they reach and endanger work zone flag operators. The IDL system successfully alerted drivers during prototype testing. Future development needs to ensure the system is crashworthy, can be produced cost-effectively and contains few components so it can be used in mobile operations.
